SPECIFICATION arming part of new. Patent No. 504,504, dated. May 24,1898.

' l ma... fild April '28, 1897 To all whom it may concern: j

Be it known that we,-DANIEL.HARRIsoN SIMPSON and J OHN- WALKER, residingat Gheadle Hulme, in the county of Chester, JOSEPH STRANG, residingat-Entwistle, and FRANK FARNWORTH, residing at Ramsbottom, in the countyof Lancaster, England, subjects of the Queen of Great Britain, haveinvented new and useful Improvements in" Machines for-Washin gCalico-Printers Blank ets, of which the following is a specification.

The object of our improvements is theconstruction of a machine forwashing calicoe printers blankets which performs its work moreeffectively and expeditiously,which will not wear the blanket, andwherein the brushes" will last much longer than heretofore has been thecase. We attain this object by the mechanism illustrated in theaccompanying two sheets of drawings, in which.

Figures 1 and 2, Sheet I, are respectively II, a longitudinal section,of our improved machine for washing calico-printers blankets. Figs. 4,5, 6, 7, 8, and 9 are views, on an enlarged scale, of some details; andFig. -10 is across-section of a modification of our improved machine.

Similar letters refer to similar parts throughout the several views.

In carrying out our improvements and referring to Figs. 1, 2, and 3, ais the wash-box, having a liquid-outlet b, inside of which box areadapted to rotate in close proximity to each other guide-rollers c 0,over which the blanket d to be washed runs, being guided into and out ofthe box a bymeans of the carrier-rollers e and f, respectively. The saidguide-rollers are all situated on one side1l.e., at the back of theblanket d-the rollers cbein g stationary and the rollers 0' arrangedbetween the same and rendered adjustable against the back of the blanketby mounting the respective ends in the block-bearings g, which aresimultaneously adjustable on the ends of the box a, so as to cause therollers c to beset perfectly parallel with the rollers c and brushes 1,hereinafter described, which is a very important feature, as the workingSerial No. 634mm on model.)

surface ofthe blanketwill be acted upon by thesaid brushes uniformlyacross its whole width. This adj ustmentis effected by means of screwsh, furnished with bevel-pinions 2', gearing into bevel-wheels 11, fixedupon a shaft k, mounted in the ends of the wash-box a and rotated bymeans .of a hand-Wheel is from the outside. Opposite, between all or anumber of the stationary and adjustable guide-rollers c c, we employ abrush l, in the present instance a rotary one, mounted in bearings Z,also secured to the ends of the .wash-box a and geared up by spur-wheelsm,

actu'atedby a wheel 0%, secured upon the driving-shaft n of thewashing-machine. In connection with each of the said brushes areemployed water-jet pipes 0, which supply the same'with water necessaryfor washing the blanket d. Opposite between the first carrier andguide-rollers e and c is fixed into the wash-box a a stationary brush1), consisting of a series of'rubber or the like strips 19, secured to awood or other suitable back, or in lieu of the said strips thebrush-back may be furnished with rows of bristles. Between the ends ofthe wash-box a is fixed below the brush 1; a board or plate g, whichforms a trough 1", having an outlet 3 at one end, and above the brush 1)is employed a water-jet pipe 0'.

' The brush 1; we formin two lengths,as shown in Figs. 4 to 8, which arejoined together and rendered reversible to insure equal wear. Its rowsof bristles or strips 19' are formed diagonally in left and right handfashion, which has the effect of expanding the blanket, and thus free'itfrom creases or scrimps. The saidrows or strips may extend across thewhole width of the brush, as shown in Figs. 4c, 5, and 6, or they may bedisplaced, as shown in Figs. 7 and 8. Instead of the brushes p andZhaving rows of bristles or rubber or the like strips such rows may beused in combination. The said brush and jet-pipe serve to softenandremove thebulk of the dirt adhering to the working surface of theblanket as it enters the wash-box a and the said trough to catch and runoff the said dirt,

and thus prevent same falling onto the adjacent brush Z and mixing withthe liquid in the box a in cases where a certain quantity is allowed toremain therein and the brushesv Z dip into same. After leaving thebrush 1) the working surface of the blanket is subjected to the actionof the rotary brushesl and water-jets 0, which thoroughly cleanse it,and before leaving the wash-box the water adhering to the blanket isremoved by means of a brush Z or other suitable device adapted to rotatein contact therewith, splash-boards t if being arranged, respectively,in connection with the rotary brushes Z and Z which receives the waterand dirt removed by same, respectively.

It will be readily seen from the drawings that the disposition of therotary brushes Z relative to the guide-rollers c c and the blanket d issuch as will allow the latter to yield to the pressure of the rotarybrushes Z and that by adjusting the rollers 0 such pressure can beregulated at will in accordance with the amount of dirt to be removedtherefrom-21c. in the washing of blankets used in heavy printing morepressure is required than for such used in light printing, and theblanket is thus subject to less wear than heretofore has been the caseand rendered more durable.

According to a modification of our lHVBH'.

shown in Fig. 9, with a single ordouble set of rows of bristles orstrips and with perfoarranged. stationary and the brushes Z renderedadjustable against the blanket in the same manner as guide-rollers c.

What we claim as our invention, and desire to secure by Letters Patent,is-

1. In a machine for washing calico-printers blankets, aradially-adjustable guide-roller mounted between two stationaryguide-rollers adapted to operate upon back of the blanket, incombination with a brush mounted between the said adjustable and one ofthe said stationary guide-rollers adapted to act upon the face of theblanket, all substantially as and for the purpose set forth.

2. In a machine for washing calico-printers blankets, in combinationwith guide-rollers and brushes between which the blanket runs, astationary brush 1) supplied with liquid and a trough r, 8, below thesame, said trough being adapted to receive the material from the blanketindependent of the main wash-box and to convey the same away withoutentering said wash-box, substantially as and for the purpose specified.

3. In a machine for washing calico-printers blankets, in combinationwith the wash-box and guide-rollers over which the blanket runs,stationary brushes Z and p made in two lengths placed end to end andhaving right and left hand fashioned rows of bristles or strips, saidbrush extending parallel with the rollers, the said two brush partsabutting against each other and being reversible, all substantially asand for the purpose set forth.

In witness whereof we have hereunto set our hands in presence of twowitnesses.
